  • Water and environment in mass media

    We kindly invite you to take a stroll around the contents of Spanish general-interest media. How many themes related to environment did you see? And, from among them, how many were good news? Usually, except natural catastrophes, we can’t find so many news in the press related to the water and the environment on other season. Droughts and restrictions, eternal transfers in the Mediterranean ...

  • What classifies as water pollution and why is it an issue?

    The UN declared 2005-2015 as the International Decade for Action ‘Water for Life’. Yet each day thousands of people still die as a result of contaminated water. This does not even take into account the millions of organisms that perish every year thank to polluted water sources. Water pollution is a huge issue that is made more so by the fact that unfortunately, water is ...

  • Biological Filtration: Future of Drinking Water Treatment

    Water is essential for all human life on the planet, but the fresh water supply is limited and is susceptible to being contaminated by all manner of toxins like arsenic, calcium, and mercury. There are many techniques to remove contaminants, including popular methods that add chemicals to balance others out, but one that not many people understand is biological water system filtration. ...

  • Water & Rivers Commission

    The Water and Rivers Commission manages the water resources of Western Australia with an area of about 2.5 million square kilometres. The Information and Systems Group in the Hydrologic Measurement Support Section at the Water and Rivers Commission maintains data archives SWRIS (State Water Resources Information System) and Hydstra. SWRIS is used predominantly for the storage of water quality ...

  • The River Segura: reclaimed water, recovered river

    The Region of Murcia is located in southeast Spain, an area known for structural water stress. The most important water source that runs through the Region is the Segura River, which is the main irrigation water resource. Late last century there was a significant environmental problem in the Segura River caused by an increase of inadequately treated wastewater discharges, in a period of low flow ...

  • The impact of farming on river banks on water quality of the rivers

    Abstract A study was carried out in a strip of a river in the dry and rainy seasons to assess the effect of farming along river banks on the quality of water in rivers. The results showed that there was an increase in the concentration of nitrate in the water downstream in both the rainy and dry seasons. In both rainy and dry seasons, the total nitrogen in the soil was highest (p ...

  • River Basin

    A river basin is an extent of land where water from rain and melting snow or ice drains downhill into a body of water, such as a river, lake, reservoir, estuary, wetland, sea or ocean. The river basin includes both the streams and rivers that convey the water as well as the land surfaces from which water drains into those channels, and is separated from adjacent basins by a drainage divide. The ...

  • River Monitoring

    The monitoring of River water has impications not only on the environmental impacts of heavy metals but also upon the quality of drinking water. THis case study covers an analyser installed in a remote location using low voltage power supplies to suppliment the local mains power supply which cannot be relied ...

  • Water Quality Parameters Along Rivers

    Water samples have been collected from a part of Surma River along different points and analyzed for various water quality parameters during dry and monsoon periods. Effects of industrial wastes, municipal sewage, and agricultural runoff on river water quality have been investigated. The study was conducted within the Chattak to Sunamganj portion of Surma River, which is significant due to the ...

  • Microbiological water quality of the Nišava River

    Microorganisms are the ideal indicators of the organic pollution of the surface waters because of their ability to promptly respond to environmental changes. Due to poor economic situation and lack of law implementation, most wastewaters in Serbia are released directly into a surface water recipient without any, or a limited, treatment. This practice has created numerous highly polluted ...

  • Portneuf river basin - USA

    The monitoring program for the Portneuf River Basin enables stakeholders to assess and document the influence of natural and human-caused factors on water quality. The program is a cooperative effort of private industry, educational institutions, scientists, and government agencies at numerous levels (City, County, State, Tribal, and Federal). The following agencies cooperate in the Portneuf ...

  • The Sustainable Use of Water in the Lower Colorado River Basin

    A long history of conflict surrounds the Colorado River. Throughout the first part of this century, disputes generally arose over securing rights to use the river’s water. Later, disputes centered on finding ways of developing and ...

  • Treatment of polluted river water by a new constructed wetland

    Abstract: A new constructed wetland was built to purify one polluted river in Taiwan, and this study was conducted to evaluate the treatment efficiency of the wetland. Due to the very limitation of available budget, several water quality items, which were stipulated by Taiwan’s Environmental Protection Administration for rivers, in the influent and effluent of wetland were analyzed and ...

  • The influence of lagoon on neighboring rivers by water and sediment quality

    Canonical discriminant analysis (CDA) was applied in order to distinguish the water-quality and the sediment-quality parameters from neighboring rivers, and to recognize similarities of water and sediment properties between a lagoon and neighboring rivers. Two set of constructed discriminant functions showed a marked contribution to most of the discriminant variables. In water, the significant ...

  • Continuous water quality monitoring on Kolubara River

    The first automated station for water quality monitoring located in Beli Brod on the Kolubara river has launched on July 2008. The station was established as the result of RHMSS participation in Twinning project financed by EU, where RHMSS was entrusted with the Component 2 of this project. Installed equipment continually records values of water level, temperature, pH, electroconductivity and ...

  • Application of membrane processes in fractionation of elements in river water

    The influence of wastewater treatment plant (WWTP) effluents from one microelectronic industrial zone on element concentrations and partitioning in river water was investigated. The stepwise membrane filtration is used to distinguish different size fractions including large particulate (>18 μm), particulate (0.2–18 μm), colloidal/nanoparticle (10 kDa–0.2 μm) and truly dissolved fractions ...

  • The impact of fluctuation of the Nile River level on water composition

    This paper studies the influence of fluctuation of the Nile River level on water composition. The Nile River could be classified to four periods according to level. The periods are flood, intermediate, drought and intermediate. The present study investigates the biological and chemical analysis of water at all periods of the Nile River. The results show that the algae count ranged from 221 to ...

  • A hydrodynamic water quality model for propagation of pollutants in rivers

    Numerical modelling can be a useful tool to assess a receiving water body's quality state. Indeed, the use of mathematical models in river water quality management has become a common practice to show the cause-effect relationship between emissions and water body quality and to design as well as assess the effectiveness of mitigation measures. In the present study, a hydrodynamic river water ...
